Timeline.

	* handles.c (_wapi_handle_unref): Reset the private record's type
	(CloseHandle): Check for a fd mapping failure, and return FALSE.
	(_wapi_handle_process_fork): Fix long-standing bug in checking
	handle return values.  Also do the required bookkeeping with the
	new process's handles.

	* daemon.c: When creating a new process's handles, check whether
	the shared space needs to be increased

	* process.c (ves_icall_System_Diagnostics_Process_Start_internal):
	Close the new process's thread handle, as we don't use it.  The
	handle stays around forever otherwise.
